给定一个文件 file.txt
,转置它的内容。
你可以假设每行列数相同,并且每个字段由 ' '
分隔。
示例:
假设 file.txt
文件内容如下:
name age alice 21 ryan 30
应当输出:
name alice ryan age 21 30
# Read from the file file.txt and print its transposed content to stdout.
awk '
{
for (i=1; i<=NF; i++) {
if(NR == 1) {
res[i] = re$i
} else {
res[i] = res[i]" "$i
}
}
}END {
for (i=1;i<=NF;i++) {
print res[i]
}
}
' file.txt
